What are the current battery recycling methods?

Battery recycling industry can ensure the safety of the industrial chain, while realizing the recycling of renewable resources, lithium battery recycling equipment through the dismantling and recycling and ladder utilization of waste lithium batteries into treasure.

1 Cascade utilization: There some wasted batteries of remaining capacity is high, the overall meet the use of demand for decommissioned power batteries appropriate repair, unified standards, put to low requirements of the battery field for secondary use, such as energy storage, low-speed car, base station substation and other scenes. However, in June 2021, the National Energy Administration organized the drafting of the "new energy storage project management specifications (provisional) (draft)", which requires that, in principle, no new large-scale power battery laddering energy storage projects. Considering the specification, the battery secondary utilization market will be greatly reduced. Generally speaking, lithium iron phosphate batteries are suitable for secondary utilization scenarios due to their high cycle life and good thermal stability.

2 Dismantling and recycling: The power batteries that have been scrapped are centrally recycled, and the nickel, cobalt, manganese, copper, aluminum, lithium and other metals in the batteries are recovered through lithium battery recycling equipment, and then these materials are recycled. Corresponding to lithium iron phosphate batteries, ternary batteries have high content of rare metals, high recycling value, and less cycle life, poor thermal stability, more suitable for dismantling and recycling.
3 Currently, the recovery rate of lithium carbonate in the battery recycling industry is around 85%, but some companies have mastered advanced recycling technology. Lithium carbonate recovery rate of some companies that have mastered advanced recycling technology is above 90%, assuming that due to technological progress, the industry average lithium carbonate recovery rate will reach 91% in 25 years, and 91% in 28 years. Assuming that due to technological progress, the industry average recovery rate of lithium carbonate will reach 91% in 25 years and 96% in 28 years.
Currently, the wet recycling technology of nickel sulfate and cobalt sulfate has been very mature, with the recovery rate above 90%, and some companies have reached 98%. The recovery rate is above 90%, with some companies reaching 98%. It is assumed that the industry average recovery rate reaches 98% in 24 years and maintains 99% recovery rate after 25 years.
